They use third-party software like Docker or Kubernetes to simplify their administration. There are workarounds: I can use the perf_events cgroup ID, provided the container software is configuring it (they do). At my employer we sometimes use SR-IOV for direct network interface access, and NVMe for direct disk access.

Sites that use an excess of resources, whether on the network or on the device, don’t just cause slow experiences, but can leave entire groups of people out. I recently profiled a page on a Pixel 2 (released in 2017), and an Alcatel 1x (released in 2018). Mbps download speed Jake Archibald mentioned his relative getting or the 0.8

A 2017 study by Akamai says as much when it found that even a 100ms delay in page load can decrease conversions by 7% and lose 1% of their sales for every 100ms it takes for their site to load which, at the time of the study, was equivalent to $1.6 Speed is also something Google considers when ranking your website placement on mobile.

Web development is evolving at a rapid speed with each passing year. And so, it optimizes the page loading speed and reduces the bounce rate. So it is convenient for all to use irrespective of internet speed and it works offline using cached data. Twitter Lite PWA : It was integrated as the standard User Interface in 2017.

De-duplication can prevent multiple copies on disk, but we're out of luck on reducing network costs. Having worked on browsers for more than a decade, I think it would be shocking if a browser team agreed to more than 10 MiB for a feature like this, especially if it won't dramatically speed up the majority of existing websites.

Today, this makes concurrency more important than ever, because it delivers two things: It hides latencies we have to deal with and cannot remove, from disk I/O latency to speed-of-light network latency; and it makes our code responsive by not introducing needless latencies of our own even when we’re not hiding someone else’s latency.
